My husband has prostate cancer and it has spread to his bones.  He has undergone a 30 week course of chemotherapy which ended in March 2017.  Following this he went on a cruise to recuperate but became ill while away and since his return has developed a chronic problem with his stomach resulting in his needing to eat frequently but following food, whatever it is, he feels chronically nauseous and burps constantly.  He was given some medication by his GP to help with the nausea but it only seems to have made things worse.  The irony is that he had no nausea while he underwent the chemo but it is now seriously blighting his quality of life.  Can anyone help?  Thank you if you can offer advice.
